I’m making a sitemap in LibreOffice Draw. I would like all the boxes to be the same width (their height can vary with their contents). I can select a lot of items and make them all a bit wider or narrower than they already are, but I can’t seem to say “make each of the selected items 35px wide” – when I paste formatting from one text box to another, the color and font do change but the width does not.
You can use the extension “One Size” which will solve your problem. It’s pretty much self-explaining.
